ADJUSTABLE W INDOW-SCREEN AND FLYTRAP.

To all 107mm t Imay concern Be it known that I, HoR'AoEE. JOHNSON,v

a citizen of the United States, residing at Bustleton, in the county of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in Adjustable IVindow-Screens and Flytraps, of which the 'following is a specication. Y

My invention relates to newl and useful" improvements in adjustable window screens and ly traps, and has for its objectto provide an exceedingly simple and effective device of this character -comprising two members or frames hinged together along one edge and provided with means tor'holding them in a closed position, each ot said fra-mes carrying a suitable foraminous -material, such as wire screen, one of said screenshaving conical shaped depressions or passageways yprojecting inwardly and located in a numberYV ot' dierent positions, lthe other screen carrying` suitable means to lure flies or other insects within the compartment between the two screens, from which placethey cannot escape and may be killed in any suitable manner after which they may be removed by opening the frames. One of said frames also carries a pair of oppositely disposed spring actuated adjustable slides, said slides carrying a suitable foraminous material, such as wirescreen, the inner edge of which is protected and( strengthened by a metallic strip or shield.

With these ends in view, my invention consists 1n the details of construction and combination ofv elements hereinafter set forth and then specifically designated by the claim. Y l Y In order that' those skilled in the art to which this invention appertains mayl underdescribe its construction'in detail, referring V by numeralA to the accompanying drawing forming a part ofv this application, in which-f Figure 1, isa front elevation of an. adjustable'window screen and fly trap made in accordance vwith my improvement.

Fig. 2, is asimilar view with one or' the frames partly open to more clearly illustrate the construction.

Fig. 3, is an enlarged side elevation of one form of conical passageway or inlet.

Fig. 6, is an end view thereof.) Fig. 7', is an enlarged edge view ofthe window screen and fly trapl Fig.' 8, is an enlarged section on the line 8-8 of Fig. 1.

Fig. 9, is'an enlarged elevation of a .por-

tion of the screen, the facing strips being removed from the stationary 'frame to clearly illustrate the. internal construction; and' Fig. 10, isa ragmental sectional view von the line lO-lO of Fig. 9, the slidebeing l `Each of the rails 3 and 4: between its inner vtace and the groove 9 isvprovided with a slot 10 running longitudinallyinward a de'- sirable distance from the'ends of the rails.

In these grooves 9 in the rails 3 and 4 are slidably mounted the arms vl1 formed in'- tegral with and projecting from the top and bottom members 12 of the' adjustable slides 13, said arms being of the same thickness as said members 12, but of less width, thereby producing shoulders 14k adapted .to contact with the shoulders 15 `formedv by the cutaway portions in the rails 3 ande; to

limit the inward movement of the adjustable slides 13. y y

Each yof the arms 11 is provided with an elongated notch 16, thereby forming shoulders '17 and 18 which are adapted to contact with' a pin 19 carried by the rails 3 and 4r and projecting across the groovestherein tor further limiting the movements of the adjustable `slides in either direction.A The lbalance of each of the adjustable slides com prises a side member' 2O attached to the outer ends of the end members 12. All of the members of each adjustable slide have a suitable foraminous material 21, such as wireI screen secured thereto, the inner edge being protected and strengthened by a metallic strip 22 attached thereto.

When the adjustable slides are -orced inward to decrease the sizeof the window screen the'w-ire screen 21 slides'in the slots 10 'and such inward movementcompresses the springs 23, one of which is mounted in each of the grooves9 with the ends in engagement with the inner ends of the arms l1 and by the expansion ofthe springs 23 the adjustable slides are forced outward.

The springs and arms of the 'adjustable slides are inclosed and held in position by thev facing strips 5 and 6 and tovthese facing strips secured the foraminous material 24 such as Wire screeningand theedges j thereof may, if yfound desirable, be covered and protected by beading 25. To the inner face of this wire screen 24 and proj ecting inwardly therefromY are secured a number of bait holding members 26 each preferably formed from foraminous material such as wire screening having the strands of wire projecting free' at Veach end as indicated by 27. the free ends of the strands at one end of the' bait holding member being used to attach said bait holders to the wire screen. whilethe free ends'of the same strands at the opposite end of the bait holder are used for securing a lure thereto.

To the bottom rail 4 areattached suitable hinges 28, said hinges also being fastened to the swingingk fran'1e29, the same being locked closed to the stationary frame 2 by a suitable hook 30 pivoted to the top rail of the frame 2 and arranged to coact with a'pin 31 carried bv the swinging frame 29, said hook and pin being situated in depressions as plainly shown in Figs. 2 and 7. The swinging frame 29 comprises Va top member 32. a bottom member 33 and side members 34, said side members carrying fillers 35 which fill the spaces between the screening of the adjust-able slides and the side members of the swinging frame the entire height of the window screen between the rails 3 and 4 and the space between the screens of the adjustable slides and the side members 7 is lleid by similar iillers ,36 carried bv the side members 7 with which the fillers 35 aline when the swinging frame is closed. These fillers may be formed with the members carryingvthe same or they may be separate pieces'attached thereto.

To the swinging frame is secured the foraminous material 37 such as wire screen and this wire screen is provided with conical shaped inlets Vor passageways 38 which may be formed from the screen itself by stamping them from said wire screen, so that they project inward and when the swinging frame is closed Jthese inlets aline with the bait holding members 26. These conical shaped inlets might also be madev separate from the screen and produced from foraminous material such as wire screen similar to the bait'holders with the longitudinal strands of wire projectingbevond the annular wire'strands. so as to leave free Vends 39. whereby the separable inlets as shown in Figs. 3 and 4 may beY attached to the screen 37 and surrounding openings in said screen.

From the foregoing description it will ne seen thatan exceedinc'lv simple and effec.- tive adjustable screen is produced which may be readily and quickly adjusted to it different sized windows Within certain limits, which-when-in position will also act as an insect trap, the insects being lured to the screen 37 by the bait within the clompartment formed between the wire screens 24 and 37, and as they walk over the screen 37 in an'y .endeavor to lreach thev bait, they will enter the 4inlets 38 and pass into the compartment between the wire screens. Because of the shape of the inlets 3S it very difficult for an insect such as a Hy to again find the opening in the inlets, because of the smaller size of the the inner end. i

After `the insects are trapped they may be killed in any suitable Vmanner as by throwing` hot` water .over the screen, at which time theswinging frame 34 may be unlocked and openedv forgthe ren'loval of the dead bodies.

Of course I do not'wish to be limited to the exact details of construction as herein shown, as these may be varied within the limits of the appended claim without departing from the spirit of mv invention.

yllavingathus fully described mv invention, what I claim` as rnew and use-ful, is-

A iiyscreen and trap comprising a main screen member having upper and lower and side rails,'the upper ofv said rails beine' grooved and recessed,y the side rails having cutaway portions, lateral extension screens having upper, lower and side rails, the upper rails cutawav for slidable reception in the grooves in the upper rail of the main inlet opening at screen and for abutment with the wall of the recess formed therein, a hinged screen carried by the lower rail of the `main screen liaviiiqnpner and lower and side rails and havingiopenings formed therein to admit flies, the side rails cutawav to register with the cutaway portions in the side rails of the main frame whereby to receive the side rails of the extension. the walls of the side rails being extended to form a closure between the extensions and the space between the main and hinged screen section, and screening sections secured bv the free 'ends of the wires forming the same to the main section for coperating with the iv inlet opening in the hinged screen section to lure the flies thereinto.

In testimony whereof. I have hereunto aihxed my signature in the presence of two subscribing witnesses'. V
